If enabled, PCs on the LAN can use VPN software to connect to
remote clients via the Internet connection. The protocols supported
are:
•
IPSec
IPSec protocol is used to establish a secure connection, and is
widely used by VPN (Virtual Private Networking) programs.
•
PPTP
PPTP (Point to Point Tunneling Protocol) is widely used by
VPN (Virtual Private Networking) programs.
•
L2TP
L2TP is a protocol developed by Cisco for VPNs (Virtual Pri-
vate Networks).
If enabled, fragmented IP packets are discarded, forcing re-
transmission of these packets. In some situations, this could prevent
successful communication.
Normally, this setting should be disabled.
A TCP flood is excessively large number of TCP connection re-
quests. This is usually a DoS (Denial of Service) attack.
This setting should normally be enabled.
A UDP flood is excessively large number of UDP packets. This is
usually a DoS (Denial of Service) attack.
This setting should normally be enabled.
Abnormal packets are often used by hackers and in DoS attacks, but
may also be generated by incorrectly configured network devices.
(PCs will normally not generate non-standard packets.)
This setting should normally be enabled.
